Beschreibung
Zusammenfassung:The invention discloses wet-type water meter dial vacuum liquid sealing equipment which is characterized by comprising a vacuum box and a vacuum pump, the vacuum box is communicated with the vacuum pump through a pipeline, the vacuum box is provided with a pressure gauge used for testing air pressure of an inner cavity of the vacuum box, and the vacuum box is provided with a water inlet pipeline communicated with the inner cavity of the vacuum box and the outside. A control valve is arranged on the water inlet pipeline, the water inlet pipeline is communicated with a water source, and the water source is lower than the vacuum box. The device has the advantages that reliable liquid sealing of the dial plate of the wet water meter can be completed, the liquid sealing efficiency is high, the bubble amount is small, the influence of water vapor on the vacuum pump can be reduced, and the service life of the vacuum pump is prolonged. 本发明公开了一种湿式水表表盘真空液封设备,其特征是,包括真空箱和真空泵,真空箱和真空泵通过管道连通,真空箱上设有用于测试真空箱内腔体气压的压力表,真空箱上设有连通真
